BEARING FOR SPINNING-SPINDLES.

SPECIFICATION forming'part of Letters Patent No. 272,528, dated February 20, 1883.

I Applicationfiled June5,1882. tNomodel.)

To all whom it may concern:

Be it known that 1, WILLIAM '1. CARROLL, of Worcester, county of Worcester, State of Massachusetts, have invented an Improvement in Bearings for Spinning-Spindles, of which the following description, in connection with the accompanying drawings, is a specification.

My invention has for its object to hold in a yielding manner the supporting-tube, which 10 receives in it the bearings for the spindle, in order that the said tube may yield to alimited extent in every direction, and assist in maintaining the spindle in its true center of rotation under all its conditions.

Figure 1 represents in partial vertical section a sufflcient portion of a spinning-frame, with a supporting-tube and spindle therein, to illustrate my invention; and Fig. 2, a top view, partially broken out, of one of my cases and washer therein.

The spindle a, tube 1;, and rail 0 are of usual construction. serted directly through a hole in the rail, with the shoulder 2 resting upon the top of the said rail, and the upper end of anut, (1, against the under side of the said rail. In some instances washers have been interposed between the said rail and the said shoulder and nut; but such washers, it composed of indie-rubber,

0 which is the best material, soon become worthless l'or the purposes intended by reason of the action of oil thereon.

To enable india-rubber washers to be employed at the upper and under sides of the rail 5 without being injured by oil I, by experiment,

discovered that the said washers mi ht be inclosed in suitable cases or boxes, thus entirely shielding them't'rom oil.

The case made by me consists of a flanged 4o annulus, c, and asmaller annular seat,f, fitted therein, the said seat having preferably a" flange or shoulder, 3, to act against the interior of the flanged parts of the annulus 0. Between these two parts ef, I placea washer, g,

5 of india-rubber, leaving a sufficient space at h The tube b has usually been into permit the parts of the case to bear firmly against the bottom or top of the washer without coming in contact. The end of the flange of the outer annulus above the rail terminates at little above the top of the rail, so as to per- [hit the flexible washer g to be compressed and to yield or rock as the support I) is rocked or moved. The parts ef 9 below the rail are the same as those marked efg above the rail 0; but below the said rail the said parts are inverted, the annulus e taking its bearing directly upon the said rail 0. Turning the nut d in one or the other direction compresses the india-rubber washers g 9' more or less. The support I) enters loosely a hole in the rail 0. The support b will inclose within it any usual bolster, and at its lowerend will contain a suitable step. I

I do not broadly claim an annular yielding packing arranged in connection with a boisterrail.

I claim- 1. The rail 0 and the shouldered support I) for the spindle, and the nut d, combined with the metal case composed of the parts of, and the interposed flexible or-yielding Washer contained in the said case, the case being interposed between the shoulder of the support I) and the top of the rail, substantially as described.

2. The rail 0 and the shouldered support b, placed loosely therein, and the nut applied to the said support below the rail, combined with two cases or boxes, as described, and flexible or yielding washers placed therein, the said cases or boxes being one above and the other below the rail, as and for the purposes set forth.

In testimony whereofI havesigned my name to this specification in the presence of two subscribing witnesses.

WILLIAM T. CARROLL. I
